When running resin,I get the following error:  "javax.management.MalformedObjectNameException: ObjectName: invalid character ':' in value  part of property...".  Here is others' discussion http://www.caucho.com/quercus/faq/question.xtp?question_id=1410 ref. Answer by Sam on Tue, 25 Feb 2003 12:17:07 -0800 (PST)   You are likely getting a conflicting/older jmx implementation in your CLASSPATH.  Try starting Resin with an empty CLASSPATH:  win> set CLASSPATH= win> bin/httpd.exe unix.sh> export CLASSPATH="" unix.sh> bin/httpd.sh You can start httpd with the -verbose option to see the CLASSPATH that is being used when  Resin is started.  With -verbose option,I get environment variables list as follows: java:        C:\Program Files\Java\j2sdk1.5.0\bin\java.exe JAVA_HOME:   C:\Program Files\Java\j2sdk1.5.0 RESIN_HOME:  D:\resin-2.1.6 SERVER_ROOT: D:\resin-2.1.6 CLASSPATH:   D:\resin-2.1.6\classes;D:\resin-2.1.6\lib\resin.jar;C:\Program  Files\Java\j2sdk1.5.0\lib\tools.jar;C:\Program  Files\Java\j2sdk1.5.0\jre\lib\rt.jar;D:\resin-2.1.6\lib\dom.jar;.... I think the reason is the blank in "Program Files",and the error disappear when I move jdk  to a path without blank and reset the values of environment variables above with the path.
